Walnut sits between the San Jose Hills and the Puente Hills, and its housing reflects that setting. Much of the city is single-family tract built in the 1970s and 80s on generous lots, with newer custom homes, gated communities and a few semi-rural, horse-keeping pockets mixed in. A home locksmith here has to be comfortable with everything from a decades-old deadbolt to a keypad lock tied to a gated driveway.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on one simple idea: the work should come to the customer. We are fully mobile. There is no storefront to visit, so everything happens at your property, whether that is a front door off Lemon Ave, a side gate near Pierre Rd, or a back entry on a hillside lot.
Residential work is more than getting people back inside. It covers rekeying after a move or a lost key, replacing worn or damaged hardware, repairing sticky or misaligned locks, and upgrading to better deadbolts or electronic locks. We are available around the clock, so a late-night problem does not have to wait for morning.
How it works in Walnut
- 1
Call and describe the situation
Phone (323) 997-8867 any hour and tell us what is happening: a lockout, a lock that sticks, a move-in rekey, or an upgrade you are considering. Details such as the lock brand, whether it is electronic, and whether a gate is involved help us arrive prepared.
- 2
We come to your Walnut home
Because we are fully mobile, a technician drives to you with tools and common hardware on board. We make no promises about timing over the phone, but we will keep you informed about when to expect us.
- 3
Verify and assess
Before opening or changing anything, we confirm that you live at or are authorized to access the property. Then we look at the lock, the door, the strike and the frame, since many lock problems are really alignment or wear problems.
- 4
Do the work with the least damage
For lockouts we favor non-destructive entry where the hardware allows it. For rekeying, we change the internal pins so old keys stop working. If a lock is worn out or broken, we explain replacement options before proceeding.
- 5
Test everything and hand over keys
We cycle each lock several times, test every new key, and check that the door closes and latches smoothly. With smart locks, we walk through codes and settings so you are comfortable using them.
- 6
Talk through security improvements
If we notice weak points such as short strike screws, an unreinforced frame or an unsecured side gate, we mention them plainly. Any upgrade is your decision, with no pressure.

What affects the price
- The type of work: rekeying existing locks, repairing them and replacing them with new hardware are different jobs with different material and labor needs.
- The number of locks involved, since rekeying one front door is a smaller job than an entire house plus a garage entry and side gates.
- The hardware you choose, including standard deadbolts, higher-security cylinders, or electronic and smart locks, which vary widely in cost.
- The condition of the door and frame, because repairs to misaligned doors or damaged strike plates can add work beyond the lock itself.
- The time of day and urgency of the call, as after-hours emergency service differs from a scheduled daytime visit.
- Specialty access such as driveway gates, barn latches or gated-community hardware, which may call for particular parts or extra time on site.
Why Walnut chooses us
- Serving Los Angeles area homes since 1987, with the owner, David Shar, as lead technician rather than an anonymous dispatch network.
- Fully mobile and available 24/7, so help comes to your driveway at any hour rather than waiting for shop hours.
- Comfortable with the range of Walnut housing, from older tract deadbolts to electronic locks and gated-drive access.
- Clear explanation before work begins, including when a repair or rekey makes more sense than replacing everything.
- Non-destructive methods first for lockouts, to protect your door, finish and hardware whenever possible.
- Honest security advice that points out real weak spots without pushing upgrades you do not need.
Residential Locksmith across Walnut
Walnut's character shapes the work we do. In Snow Creek, the gated community, homes often combine electronic locks with controlled community access, so a visit might involve programming a keypad deadbolt, replacing a failing smart lock or rekeying after a change in occupants. Walnut Heights, with its hillside lots and varied custom homes, brings more side gates, detached structures and larger properties where several locks need to match one keying plan.
On the north side, the Mt. San Antonio College area along Grand Ave has a steady flow of students, renters and commuters. Lockouts there often happen at odd hours, and rentals benefit from rekeying whenever tenants change. We serve addresses throughout 91789 and 91788, from the streets near Suzanne Park and Creekside Park to homes off Valley Blvd, Amar Rd and Nogales St.
In the hills toward the San Jose Hills and Puente Hills ridgelines, some properties keep horses, which means barn doors, tack room locks and long driveway gates that need dependable hardware. With SR-60 and SR-57 close by, we can reach homes across the city at any hour. Call (323) 997-8867 whenever you need a locksmith in Walnut.
